All you need to do is fill out a quick questionnaire and a simple shopping diary.
We'd like you to fill out a questionnaire about how you pay for different things – whether you pay by cash, cheque, card or even on your mobile phone. You can either do this online or request a paper version.
We’d also like you to keep track of what you buy and how you pay in a simple spending diary that we sent you in the post. In the shopping diary we’d like you to keep track of anything you spend over £1 and how you pay for it, over the course of four-weeks. Don't worry, it will only take a minute or two to fill out each day.
